Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed May 24, 1905. Serial No. 262,061.

To all whom it may concern.-

Be it known that we, BRUNO SALZER and GUsTAv WALTHER, subjects of the German Emperor, residing at Chemnitz, in the Kingdom of Saxony and Empire of Germany, have invented certain new and useful Improvements in Means of Converting Constant Oscillatory Motion into Rectilinear Motion, of which the following is a specification.

Our invention comprises an oscillating member provided with individual devices adapted to be operated independently of each other and to be severally engaged with a reciprocating member or slide to varythe degree or extent of reciprocation of the same.

Our invention in its preferred embodiment is also provided with means for automatically disengaging the said individual elements or devices from said slide.

The invention will be more fully described in connection with the accompanying draw-,

ings, and will be more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a front elevation of one embodiment of the invention. Fig. 2 is an end elevation of the same. Fig. 3 is a side elevation of the device shown in Fig. 1 with parts in section and looking in the direction of the arrow 3. Fig. 4 is a view similar to Fig. 3, showing the parts in a changed position. Fig. 5 is a modified form of the apparatus shown in the foregoing figures.

In the embodiment shown our invention comprises an oscillating arm adapted to move about a fixed axis and provided with a plurality of vertically-displaceable operating-pins. Said pins are preferably arranged in alinement extending outwardly from the axis of oscillation and are adapted to be severally engaged with a reciprocating slide. The engagement of said pins with said slide is effected by means of a selector, the latter operating upon the several pins at each complete oscillation to severally engage the same with the slide in. a manner to transmit to the latter a varying degree or extent of reciprocation. There is also provided means for restoring the pin engaged with the slide to a normal position at the completion of movement of the oscillating and reciprocating members. By these means we are enabled to accurately and effectively transmit to the reciprocating member the prescribed extent of motion desired.

Considering our invention more specifically, the same consists, as shown in Figs. 1 to 4, of the following mechanism: (1 indicates a vertically-disposed shaft provided with integral or fixed arms 0, pivotally mounted at b to stationary parts of the frame of the machine. The pivotal mounting forms the axis about which the shaft a and arts hereinafter more fully described oscil ate. Said shaft is oscillated by means of a cam 6, pro vided with a groove upon and rotated from a shaft (1, which may be connected with any suitable source of power. The upper end of shaft (1, is provided with a roller 9, which travels'in said groove. Said shaft a carries rigidly-mounted arms hh, which extend forwardly to the axis of rotation 20 :r and at an obtuse angle therefrom a suitable distance. Each of said arms is provided with a plurality of displaceable pins k, the length of said arms from the axis 90 being governed by the number of pins it is desired to use. Said pins are provided with. annular recesses Z at points intermediate of their length for engagement with yieldinglyacting retaining devices, said retaining devices serving to automatically engage the recessed portions of said pins to hold the latter in engaging or non-engaging positions and to Said cam is mounted permit said pins to be thrust into and out of I said positions. The grooves of said pins are located in a manner to form upwardly-engaging heads and downwardly-extending reduced portions. Said retaining devices consist of spring-actuated plungers m, provided with springs m. (Shown in detail in Fig. 2.) The outer end of the plunger m is rounded, and the recesses are of complemental formation to permit free engagement and disengagement of said parts.

n indicates a reciprocating member or slide with which the several operating-pins 7c are engaged in the operation of effecting a varying degree or extent of reciprocation of the slide. Said slide is provided with a slot 0, adapted when the parts are in a normal position to register with the engaging heads of the pins k, permitting any one of the latter to be thrust upwardly into the same, as shown in Fig. 1.

The mechanism for severally engaging and the same are in their normal position, whereby the selector u may be reciprocated endwise of the arm t to bringthe pin w into register with any one of the operating-pins. The slides a may be actuated by'hand or by operative parts of the machine. The mechanism herein shown for actuating said selector it comprises bell-crank levers pivoted at 3 Said levers are slotted at c to receive pins z, projecting from the outer ends of the selectors u, in order to accommodate for movement of the latter in the operation of forcing the operating-pins into engagement with the slide n; The opposite arms of said bell-crank levers are connected in any suitable manner with operating-rods or may be connected with each other if it is desired to transmit to the slide a a uniform extent of reciprocation. The devices whereby the pins engaging the slots in said slide a may be restored to a normal position consist of arms 1, rigidly secured to the vertical reciprocating rod p. Said arms are provided on their outer ends withrestoring-strips 8, adapted to be inserted within the slot 0 when the parts are in a normal position. It will be seen by reference to Fig. 1 that upon the downward movement of the rod 19 the restoring-strips s, entering the slots 0, will engage the operating-pin, forcing the same downwardly in the arm h to a normal position. The operation will be clear from the 1foregoing, but may be briefly stated as folows:

The parts are shown in their normal position in 1 and 3, wherein the pins are'in position to register with the slots 0, and the restoring-arms 1 are in a raised position. In this figure the selectors are shown as having been moved into register with one of the pins k, the rod p having been raised to force the selected pin into engagement with the slot 0. The parts are now in position to be operated. As shown in Fig. 4, the shaft a has been swung about its axis, swinging the arm it through an arc of ninety degrees, the pin 4 remaining in engagement with the slot 0, the rod 7) having been previously lowered. It will be obvious that the plate a, if engaged by pins 4, 5, or 6, would be caused to travel a greater distance than by engagement with the pin 4, and on the other hand an engagement with either of the pins 3 or 2 would cause a slightly less extent of travel of the slide a, while the pin 1, being coincident with the axis as, would not cause any travel of the slide a. It will be seen from the foregoing that the length of travel of the slide n will be equal to the radial distance from the operating-pin. to the axis a" m; The pin 4 will be retained in engagement with the slot 0 during the return oscillation to the position shown in Fig. 3, whereupon the rod 79 will descend, forcing the restoring-strips s into the slots 0 and the pins 7c downwardly into their normal positions. The selector will again be operated, as will be clearly understood from the foregoing. It will thus be seen that in each complete movement of the plate n it is not only positively driven, but it may be driven a greater or less distance, according to the operating-pin selected.

From the foregoing construction it will be noted that motion may be imparted to the slide it to cause it to move a relatively great or restricted distance, the degree or extent of reciprocation imparted to the slide depending upon the number of pins employed. How ever, it will be obvious that a certain amount of space is necessary between each of the pins 7c and that said pins by reason of their diame ter are of necessity spaced apart a slight distance. Therefore in cases where it isdesired to vary the movement of the slide 72, an exceedingly slight distance the operating-pins may be, as shown in Fig. 5, arranged in staggered order. In the construction shown in the modifiedform the arms h and shafts a are in duplicate. The operating-pins being arranged in staggered order, the pins of one arm are arranged at unequal distances from the axis of rotation of the oscillating mechanism, thereby enabling the operator, through the medium of the selecting mechanism which is likewise duplicated, to obtain a distance of travel of the plate a varying in the slightest degree desired.

Having now fully described our invention, we declare that what we claim is 1.
